djvulibre & mozilla problem

[Rich Winkel]

Hi, I'm having problems using djvulibre under mozilla.
I have djvulibre-3.5.12 and mozilla-1.6_4,2 installed.
When I try a sample document at
http://www.djvuzone.org/djvu/antics/index.html
for instance, I get a hopeful looking blue toolbar at the bottom, reading
about, help, up, digital library, and a document-specific comment.
But not the document itself, the rest of the window is blank.

Has anyone else had this problem?

Thanks,
Rich
